- How I did it (because ScHnOo asked) -
The little bot was originally sketched in pencil to get the general concept down, then scanned into the computer using my dumpy HP scanner. The process of inking and coloring the bot was performed in inkscape.

The cement-like floor and wall were made in The Gimp using noise, plasma, color adjustments, and emboss filters. I made it at a high resolution (2400x1800 or so) so it could be scaled down as well as perspective-distorted for the floor without incurring too much crapification in the process.

Paint splatters were achieved by going into my back room and dripping some 3 year old black tempera paint onto 8.5x11" sheets of printer paper and then blowing on them to produce directional splatters. The splattery papers were then scanned using the same dumpy printer, then raised their contrast in gimp. Imported the splats into inkscape, ran bitmap traces to convert them to vector shapes easily, then I placed them where I wanted and adjusted their colors to ugly lime green and pinkish.

The final steps were adding the seams in the walls using inkscape, and that's it!

I'm bad at using Illustrator or vector programs. However, you just gave me a new insight to taking advantage of the trace tool. Cause when I was looking at the paint splatter, I thought at first "Oh it's photoshoped." but when you mentioned Vector then I was like "WTF?! O_o WOW! That's AMAZING!" I know for a sure fact that doing vector combined paint splatter from scratch is not easy unless you use some stock resource. Very smart move. Going to give that a shot!

Oooooh, how cute! He has that "oops, I'm in trouble" expression down pat, too.

I remember reading a children's book about a kid going to a museum and seeing a famous Jackson Pollock picture -- and totally unimpressed, remarking "I can do that in about five minutes." Looks like this little robot has proved that.

I thought your name seemed really familiar, and then I saw you were one of the people that favorited my deviation "Bad Words." Now look at you!! This is a really nice piece, do you mind if I use it as my computers background? It would totally fit with my little motif that I have going on. Either way, I love the colors, and this is just really adorable, and just... everything all in one. Congratulations on the daily deviation, and keep up the amazing work, alright?
